Hi guys, I have posted this week's audio tracks: Track 12 is 4.1 on page 26, Track 13 is 4.2 on page 27, Track 14 is 4.3 on page 28.
I think Track 13 will help you do your first homework of the week.
By the way, your homework will be checked in the second lesson of the week, so make sure you complete questions 1 and 5 on page 27.
